Thousands of Twitch videos silenced, as streaming site mutes copyrighted audio

Game streaming site Twitch has started muting the audio of any video that is detected to include unauthorized audio—which is to say, any video that includes any reasonably mainstream background music. […] The impact of this is far-reaching, with an enormous quantity of Twitch’s video on demand (VOD) content being muted. Twitch streamers routinely listen to music while streaming, and e-sports broadcasts often play music between matches. All are now silent. This includes high-profile events such as Valve’s Dota 2 tournament, The International 4, and Twitch’s own weekly gaming show, Twitch Weekly. – Peter Bright,Ars Technica
